Abstract
The invention discloses a compound release agent for copper anode casting and a preparation method of the compound release agent for copper anode casting, belongs to the technical field of copper smelting and mainly solves the problems that common release agents for copper anode casting cannot form compact films with larger adhesive forces, copper molds are damaged due to the fact that the release agents are washed open easily by molten copper and the white plate rate is high due to the fact that the release agents cannot be separated easily when anode plates are placed in water to be cooled quickly. The compound release agent comprises barium sulfate and composition of oxides, wherein the barium sulfate is precipitated barium sulfate; the composition of oxides comprises B2O3, SiO2, Al2O3 and CaO, to be specific, in percentage by mass, 30%-70% of BaSO4, 2.5%-5% of the B2O3, 20%-45% of the SiO2, 1%-7% of the Al2O3 and 1%-8% of the CaO.
Description
Technical field
The present invention relates to Copper making technical field, be specifically related to a kind of copper anode casting compound releasing agent and preparation method thereof.
Background technology
In existing Copper making technique, Outokumpu Rotating caster has been widely used in copper anode casting.The mould-type that Outokumpu Rotating caster uses is divided into punching block and copper mold, in production process can not there is the phenomenon of positive plate sticking to mould in punching block, but punching block damages Hou Tong manufacturing enterprise cannot complete reparation and processing, must arrive the processing of other relevant enterprises, incur loss through delay manufacturing schedule, increase production cost.And after copper mold damage, can be cast by manufacturing enterprise's self-organization, substantially increase and produce facility.
Owing to there is larger thermograde between copper water during casting and copper mold, thus the local melting and positive plate of copper mold is bonded together, and the existence of releasing agent can optimize copper mold and positive plate departs from situation, reduce or avoid the generation of mold sticking, and cover the physical specification that the smooth releasing agent of mould effectively can improve positive plate and make positive plate more smooth, good separation layer can also be formed between copper mold and positive plate simultaneously, play heat-blocking action, thus the failure effect reducing copper mold to reduce because temperature field raises repeatedly and cause.Require in production practices that releasing agent will have stability at high operating temperatures, can not react with copper water.The copper coin of cooling forming can be made preferably to deviate from from copper mold.At present, in domestic and international cupper smelting, widely used releasing agent has barium sulfate, blanc fixe, bone meal, clay powder etc.But using existing any releasing agent all to there is external form quality, undesirable (blank rate is high, namely release agent residue enters electrowinning process on positive plate), the de-phenomenon of generation sticking to mould difficulty, moisture evaporate positive plate not in time and produce the problem such as pore, bubbling.
Therefore a kind of novel copper anode casting releasing agent is developed significant.
